The Software-Defined VNA:
**Example: S11, S12, S21, S22 for 201 frequencies in exactly 22ms on a Windows 7 PC, without using segmented or adaptive point lists.
With direct hardware programming in C/C++, Python, LabView (optional), and other languages on request. there is no legacy scripting, no middleware and no USB communication delays, the AKELA VNA is perfect for high-volume or high-mix manufacturing.
AKELA VNAs are unique in being fully controlled by an API (Windows or Linux) which has direct access to the hardware, without any middleware such as SCPI or COM/DCOM required to emulate traditional "button-pushing".
This allows the hardware to run product-specific tests at blazing speeds, then transfer data via Ethernet from one or more VNA(s) to a PC for user-specific analysis and storage.
The result is lower costs, both per VNA and per test, plus better information about each DUT, since there is no middleware in the PC or "box" to slow software execution. (See the API here) For example, a minimum of two parameters are downloaded to define a sweep:
- Frequencies (linear, segmented, adaptive or a custom list)
- Hopping rate
Raw data is transmitted back to the host PC for full 12-term correction with AKELA's or custom algorithm in real time, or post-processed after storage.
Combined with outstanding reliability – over 14,000 hours of zero failure testing in hostile field environments – and fast setup using the standard API or executable setup software, AKELA VNAs provide unmatched value for production testing.
